    def render(self, _, value, attrs=None):
        return value

In the form:

my_read_only = CharField(widget=ReadOnlyWidget())

Very simple - and gets me just output. Handy in a formset with a bunch of read only values. Of course - you could also be a bit more clever and give it a div with the attrs so you can append classes to it.
